Product Introduction
【Product use】
The orbital ball valve series is a new type of pipeline valve developed and designed by our company with the introduction of foreign advanced technology. This valve is a top loading and unloading forced sealing ball valve; it has online maintenance function.This valve has a unique sealing structure. When the valve is closed, it is mechanically and forcibly sealed, and the sealing is reliable.During the opening and closing of the valve, the sealing surface composed of the valve seat and the ball core is frictionless.The valve has a long service life and the switch is easy to operate.The valve seat and the ball sealing surface are respectively made of surfacing cemented carbide and supersonic spraying tungsten carbide to ensure that the ball valve seat will not bite or scratch, and at the same time it has wear-resistant and scouring-resistant functions.It is suitable for regulating, opening and closing pipeline fluids in natural gas, oil products, chemical industry, metallurgy and other industries. Among them, the anti-sulfur series products are suitable for long-distance natural gas pipelines containing hydrogen sulfide media, many impurities and serious corrosion.
【Product features】
1.The static single-run seat structure can ensure that the two-way sealing is tight and reliable and zero leakage is achieved.
2.The top-mounted design allows the system to be repaired online.
3.The cam mechanism at the lower end of the stem can provide a mechanical wedging force to ensure continuous tight sealing.
4.The opening and closing process is completed in two stages, and the lifting stroke is short and easy to operate.
5.During the opening and closing operation, the sealing surface must be completely out of contact, no wear, low operating torque and long service life.
6.The space formed with the valve seat during the rotation of the sphere increases the flow rate of the medium in the channel, thereby achieving the effect of cleaning and sealing.
7.The fire-resistant design of the ball valve implements standards such as API607, API6Fa and JB/T6899. In the event of a fire and the soft seal is burned, the fire-resistant structure of the ball valve can prevent a large amount of leakage of the medium and prevent the fire from further expanding.
8.The valve drive devices are manual, worm gear drive, electric, etc., which are easy to operate and reliable to install.
